A method on the evaluation technology of high speed railway infrastructure safety state

High speed railway plays an important role in the national transportation artery. Currently, high speed railway infrastructure safety status directly related to the safe operation of high speed railway. However, in the study of evaluation research on the high speed railway infrastructure safety state, few domestic and foreign scholars studied the problem systematically and comprehensively. According to the phenomenon, this paper carries on the classification based on the different characteristics of high speed railway infrastructure, which is used to summarize the evaluation indexes of each part of infrastructure. Then the evaluation system of high speed railway infrastructure safety state is established with the ideal point method and AHP analysis to apply to evaluation technology of high speed railway infrastructure safety state.
